Basics of Space Flight: Rocket Propulsion

Specific Impulse. The specific impulse of a rocket, I sp, is the ratio of the thrust to the flow rate of the weight ejected, that is where F is thrust, q is the rate of mass flow, and g o is standard gravity (9.80665 m/s 2).. Specific impulse is expressed in seconds. When the thrust and the flow rate remain constant throughout the burning of the propellant, the specific impulse is the time for ...
